This; invention relates to'l new and, usefulv improvenientev in shaving razors, and, moreparticularly,l the aim is toV provide a novely and' valuable' razor-"characterizedaby the inclusion of amanualv actuator to be-intermitt'ently oscillatably oper' ated, a train of gears for being continuously driven by' `intermittent` operation' of said actuator', and' a; plurality of` cutting? blades; toI be simultaneously rotated by said gear train.

The new razorv isof the' so`ca11ed hoetype, having a handle@ andi` above the? latter al head carryingfthe cutting means. finely; multitudinouslyA perforated top shaped? to c'onform-` toA thepa'th ofi` travel` of the cutting edges of the cutting means,` and, therefore; rr'tliis respect,` also, the newrazor is` analogous to the 1so`calle`d electricrazbrl l A` special" feature ofi the present invention' isv that the cuttingmeans isrcomprisedKA of al plu rali't'yv` of thin" iiat blades, theseadapted to` be afiixed tov a`y` common revoluble carrier;` and?l the arrangement isf suchl that;when said carrier as driven by thelgear` train is rotated, the blades are bodily' movedA through: circularly orbital` pathsl concentric i withl thefiaxis'l of suclrotation; therebyhavethe cutting meansA incorporate a plurality of whirling blades:

Saldi bladesmay' be arranged radially ofV said axis, or arranged at angles to such planes.lbut, asv herein shown, they are in placesradial to said axis;` and whilefas :many blades asdesir'ed may be used, they are' herein shown', for example,` as present to such' av total as toT-h'ave' each blade, of

a circumferentially arranged series of them over i a predetermined 1ength,i"'1engthsubdivision, of the-carrier',`` at 90"spacing's one from another.

Another feature of the inventionisthat 'any `of saldi blades4 is4 readily removable; for discardingtheflsame and-the substitution of a new blade`, or

for rsharpening and replacement thereofon the carrier: and-'in this l connection another object is. tof provide a carrier such that-- the blades may each'` be estendere blade such asisV new' com monly sold" at t'riiiing"A costff fori feweshave use in suchv welll-knownI hoe type razors' as the Gillette,

Fig. 8- isa somewhat diagrammaticfview, illus trating a modification.

The'A shaving razor, according to: theV xnodiiicar` tion ofthe invention showniin Figs. 1- to 8f, includes a hollow` casing formed of two opposed molded-shell-like portions l5l and I6, and a-y cap sectionl Hp The portions I5 and I6 may be.V

molded of asuitablesynthetic resin or plastic. The` cap section l1 is preferably made oigl very thin sheet metal and providedwitha plurality of smallperforations I8, in the manner familiar in the electric-shaver art. f

The casing portionsA i5 and i6 aresubstant-ially.` duplicates; except that it is the portion I5 only which lis provided interiorly with a pair oijbosses I9 andrZ (Fig, 1)" and except that it the-portion I6 only which is provided'witha-boss 4I, see

Fig. 2,; although, aswill beunderstood, oneof theportions I5 and I5 is formed' tothe right handand?` the other of these portions4 is formed to the left hand.

The; purpose" of the boss last-mentioned willl be `explained later; but, now referring tol the bosses ISNand 20, the casing portion [5L is apertured` in line with the center linesfof these bosses',` and suclr apertures are continued as` bores: through.l the said bosses, so that, before thecasv ing portions I5 and I6 are coupled, screws 2| and 22 (Figs. 1 and 2) may be employed for engagement with internally threaded necks 23 and 24 (see also Figs. 3 and '7) integrally projected from a plate 25.

On said plate 25, as by way of a stub-shaft 26, a spur gear 21 is rotatively mounted; also, as by way of a stub-shaft 28, another gear 29 meshes with the gear 21; and also, as by way of a pivot pin 30, a suitable spring urged pawl 13I is rotatively mounted on one side of spur gear 21. 'This pawl is for permitting rotation of the gear 21 only in one direction, that indicated by the ar-v row 32 in Fig. '7; said pawl engaging the teeth of a multi-point star wheel 33 fixed to the gear 21, as at :34, for rotation therewith.

Half formed along an edge of the casing portion I5, and half formed along a matching edge of the casing portion I6, is a slot 35, for providing a field of oscillation for a manual actuatorV 36 for the gear 21; such actuator pivotally mounted as at 31 and rockably carrying a starwheel segment 38 resiliently urged to meshing relation, rack and gear fashion, with the star wheel 33. At its lower end, the actuator :36 has a lip 36d providing the upper wall of a recess formed'in the actuator and wherein lies the end of the segment 38 where the latter is pivotally mounted on the actuator at 36h; there being a wire spring 36c for urging the teeth 36a of said segment into meshing relation with the star wheel 33. Thus, on an inward stroke of the actuator 36, the segment 38 will drive the wheel 33 in the intended direction, while on an outward stroke of the actuator, said segment, unable to reverse the direction of rotationA ofsaid wheel because of the pawl 3I,idly moves outward, with the wheel 33 meanwhile rotating as before under momentum.

The actuator 36 is, when unlatched, normally urged to its full line position shown in Fig. 2, by an'expansile coil spring 39, one end of which engages an L-pin 4I] fixed in the aforesaid boss 4 I, and the other end of which engages a straight pin rearwardly offset from the actuator 36.

In order to hold said actuator 36 retracted, as indicated in dot anddash lines at 36' in Fig. 2, the .actuator is-transversely slotted as at 143;' this slot being so placed that when the actuator is thus retracted, said slot is, as'indicated at 43', in line with the upper end of a catch 44 slidably mounted, as by a pin and slot connection indicated at 45, on a projection 416 partially integral with the casing portion I5 and partially integral with the casing portion I6. Said projection at opposite sides has upstanding ears 41 for holding the catch 44 to straight-line sliding movement, into and out of the slot 43.

VThe casing portions I5 and I6 are coupled by rivets or the like 48, 49 and '50, these respectively sent through matching apertures in the matching pairs of ears 5I, 52 and 53, one ear of each pair being integral with the casing portion I5 and the other ear of each pair being integral with the casing portion I6. Y v

Following securement in the casing portion I5 of the plate 25 and its carried parts. by the screws 2I and 22 as explained, and incidental to coupling of the casing sections I5 and I6 as just above described, the actuator 36 is pivotally mounted on the pin 31, and the cutting-means carrier (Figs. 3 and 4) is placed in operative position by mounting the opposite ends of a carrier-shaft `54 in sutablajournalling means in said casing portions. On said shaft, at its cen- Referring next particularly to said carrier and to the cutting means as these are shown in the embodiment illustrated, and in lthese connections referring especially to Figs. 3-6, at each opposite side of the gear 55 is one of a pair of like carrrier sections 56 and 51, both these sections, like said gear, suitably fixed on the shaft 54. Each carrier section is shaped for having four cutting blades removably mounted thereon. To clarify the drawing disclosure, the carrier section 56 only is shown as having its blades, respectively marked 58, 59, 60 and 6I, in place thereon. Each of the two carrier sections I56 and 51, over each of the four quadrants of the cross-sectional aspect thereof, is identical; with, at each of said quadrantal cross-sectional areas, as indicated in Fig. 4, a projected formation of truncated triangular outline, in which view one of said formations is marked 62.

Each such formation has a wall 63 lying in a plane approximately including the axis of the shaft 54, said plane substantially radially extended relative to said axis. Each such formation at its side opposite to the wall 63 has a wall 64 which, lying in a plane at an angle to a plane radial to said axis, may well be called a secantial plane. Each such formation also has a drilled and tapped recess E65 in its Wall 63, with the axis of said recess normal to theplane of said wall. yOpposite said Wal163, between the latter and the shaft 54, is a slot 66, this for accommodating a familiar reinforcement marked 61 in Fig. 6 and permanently afxed to the blade there shown. Said blade also is characterized by the inclusion of a substantially elongatedslot 68.' Matchingly placed relative to this slot, when said blade is properly positioned relative to the lformation 62, is a slot 69 through the outer end of said formation. The last-named slot, for that one of said formations which is downwardly directed in Fig. 4, is given the same reference numeral, 6;9, in Fig. 3. Y

Each of the just explained relative to the formation 62 or to one of the three other formations corresponding thereto, is secured in position on and locked to its carrier section 56 or 51-byan L-shaped clip 10 individual to each` blade, all these clips being alike. Each of them is apertured at 1I. and carries a projection Y12; said aperture, and projection being so arranged on a clip that when a blade and its clip are arranged relative to the carrier as shown, with said projection of said clip passing through the slot 68 of said blade and also into the related slot 69 ofy the carrier, the aperture 1I of said clip registers with the related drilled and taped recess 65 of the carrier. .ThenL merely by applying and tightening one of'the eight screws 13 with slenderized knurled heads. the blade is anchored to a carrier section.

In operation, the actuator 36 having been'unlatched from the catch 44, and with the handle portion of *the device manually grasped, the

hand of the user is intermittently flexed and reblades, having vbeen placed as Y high speed, with the cuttingedges of said blades travelling through the 4path `indicated at 14 `in Figs. 3 `and 4. At the same time, the Adevice .is manuipulated to apply the 'finely perforated cap section l1 to the face or other body `part `to be shaved, therebyto cause the too-long hair ends to enter into such perforations for being cut off scythe-fashionby the whirlingblades.

`Referring nally to Fig. :8, .this illustrates a modication in which two cutting bladecarriers are provided, one axially alongside the other. Here the parts to which are applied reference numerals with single primes or double primes added correspond, respectively, to the parts to which are applied reference numerals without primes. The parts, operativelyrbeyond `thegear 21', and to which reference `numerals with single primes areadded, are for driving the carrier for the blades 58', 59', `lill' `and Blf. The shaft for the carrier for the blades 58", 59", 60 and 6l" is indicated at 80, andthe gear, iixed on'said shaft and corresponding to `the gear 55', is marked 8 l. Interposed between the gears 21 and 8| is a pair of spur pinions 82 and 83. Thus, when the actuator 36 is operated as above described in connection with the acuator 36, the gears of Fig. 9 simultaneously rotate in the directions of the small arrows there shown, thereby to whirl all the cutting blades on the two carriers. To clarify and simplify Fig. 9, there is omitted therefrom a showing of the casing and of a plate for functioning as does the plate 25 relative to all gears other than a gear coaxial with a carrier.

While I have illustrated and described the preferred embodiments of my invention, it is to be understood that I do not limit myself to the precise constructions herein disclosed and the right is reserved to all changes and modifications coming within the scope of the invention as defined in the appended claims.

Having thus described my invention, what I claim as new, and desire to secure by United States Letters Patent is:
